The vague human feeling of the double loudness (volume) is specified
with about 6 to 10 dB. This personal feeling is not an exactly measurable value.

Conversion Factor, Ratio, or Gain to a Level Value (Decibels dB) Amplifier conversion – Convert decibels to voltage gain / loss Calculator Voltage Gain – Voltage Loss and Power Gain – Power Loss |
Voltage gain in dB |
Power gain in dB |
Voltage ratio = amplification factor (voltage) |
Power ratio = amplification factor (power) |
V1 = Vin and V2 = Vout. V2 > V1 or Vout > Vin means amplification. The dB value is positive. (+) V2 < V1 or Vout < Vin means damping. The dB value is negative. (−) V2/V1 or Vout/Vin means the ratio. The amplification or the damping in dB is: L = 20 × log (voltage ratio V2 / V1) in dB. V1 = Vin is the reference. |

MP3 Gain 4.5.0
MP3 Gain for mac is a simple tool designed specifically to adjust and normalize the volume of audio(mp3, wma, etc) files. It automatically normalize the volume of audio files and adjust the loudness of audio tracks without lossy. It performs statistical analysis to determine how loud the file actually sounds to the human ear.
Key feature:
- Support many audio formats(mp3, wma, wav, flac, m4a, ac3, mp2, ogg)
- Support batch adjustment
Note: NOT support DRM protected audio files.
What’s New:
Version 4.0.0
- Improve audio quality with new algorithms
- Easy to use with new interface.
- Support wma, wav, ac3, flac, mp2, ogg audio format gain(IAP).
- Fixed some other bugs.
